Connecting two MDS 9500

We are planning to connect to existing MDS 9509s together. Each MDS 9509 already has VSANS configured that do not overlap. We are planning to use IVR.The connection will be ISL with four E ports in single port channel group. Will the connecting of the two MDS 9509 cause a disruptive fabric merge ?


Re: Connecting two MDS 9500

If I were you, I'd wait for someone from Cisco to answer your question, but I'll make an attempt.

It can be done non-disruptively:

1. Make sure to create a new VSAN, that will act as IVR transit VSAN.

2. Turn off trunking on the port-channel before you bring it up and place the E ports into the new VSAN. This will ensure that you don't get any disruptions in your existing fabric. You did say that your VSANs don't overlap, so this step is not really necessary, just a precaution for the future scenarios.

4. Bring up the new port channel.

5. Enable IVR (not disruptive)

6. Create IVR topology database and activate it (not disruptive)

7. Create IVR zones, zonesets and activate them (not disruptive)

Again, let Cisco person confirm this.


Re: Connecting two MDS 9500

The switches will not merge until there is a common vsan between them, such as vsan 1 or some other vsan you create on both switches. That will become the transit vsan in your ivr topology. It is safe to bring up the 4 ISLs and new port-channel. But before you enable ivr and configure it on both switches please see the guidelines in MDS Config Guide and also read the SAN-OS 2.1(2d) and 2.1(2b) Release Notes to understand the important ivr fixes in those releases. If it is the first Enterprise package feature in use you will have a 120 day grace period to obtain and install the Enterprise License.

Re: Connecting two MDS 9500

We are using m9500-sf1ek9-mz.2.0.3.bin. Will the existing active zone set zones still work, when the IVR zone set is made active ?

Thanks for your response.

Re: Connecting two MDS 9500

Yes, IVR zones are a subset of the active zones in a zoneset in a given pair of VSAN's.
